From what I've read ,you shouldn't dose macros and micros the same day ,yet this mix contains K and micros.??

Hi Christophe ,Christophe;123298 said:Sounds like a reasonable bioload for your 40 liters. If your plants seem to be growing rather than melting away, that's by far the best indicator that things are going well. With lower light, though, your luck with some species may vary a bit -- especially with DIY CO2 or no CO2.
I'm doing low to medium light with pressurized CO2, things grow, but it's kinda slow for the most part. I dose x2 per week (no nitrate in my tap)
Got a nitrate test kit? That can give you a little better idea that you're in the ballpark -- here's info on calibrating it against known solutions, so you have a better idea what you're looking at:

It's still down to matching the color to some lame printed card, but it's better than nothing sometimes. You can also test the tap water to verify that the water report value is holding true.

Fermentation (DIY CO2) can easily provide 30-40ppm CO2 for a 20 gal. tank with weekly maintenance and an efficient method of dissolving the CO2 gas into the tank water.

What's your tank pH if you draw a sample and let it fully degas for 24 hrs?
What's the pH with your CO2 system working?
If you haven't seen it already, here's how to estimate your dissolved gas concentration:

DIY CO2 always seems kinda iffy to me as to whether it can deliver a high and stable enough dissolved gas level to work well. Excel worked well for me for a while, but I was more limited in what I could grow. As my plant mass increased, I began to see stunted growth, pinholes, transparent leaf patches despite all the ferts being there.

I measured GH and KH from the tap this morning with Tetra Drop Tests ,the only ones I could find at the lfs.
GH 15
KH 10
My water company says GH is 19.5 ,according to this http://www.vivaqua.be/sites/default/files/reports/2013_12/2013_12_BFI41_BXL_FR.pdf
I just measured GH and KH in the tank ,using the same Tetra Drop tests -gave me same values- GH 15 KH 10
I will measure PH tomorrow when I'll get a meter ,I don't trust my old PH pen anymore,although the results were close to when I was using JBL strips
PH was around 7.5 ,will update tomorrow.
According to the chart ,and -Assuming- that the data from the tests is exact ,a KH of 10 with a PH of 7.6 ,places me in the 9.5/11.9 crossing.From Blue to Green .....from Low to Enough,fluctuations ,can there be some truth in all of this?
